Fixed Inductors

Fixed inductors, also known as fixed coils or chokes, are electrical components designed to provide a fixed electrical current through an inductor coil. Typically these components use iron core material but they can also use ferrite or air cores depending on the application. The value of the inductance is either fixed or adjustable. The most common type of fixed inductor is the 1782R-65H.

1782R-65H Application Field

The 1782R-65H Fixed Inductor is designed for use in high power DC-DC converters, LED lighting, automotive electronics, telecommunications infrastructure, and other long range power applications. Its unique construction allows for an incredible durability in adverse conditions and its fixed value is ideal for many applications.

1782R-65H Working Principle

The 1782R-65H Fixed Inductor uses a combination of a coil design, iron core material, and two capacitors to provide great efficiency in power conversion processes. The inductor coil itself is made of three legs that are wound in such a way that the inductance remains the same. This means the inductance value is “fixed” and does not vary with temperature or frequency.The inductor also contains two capacitors. These capacitors serve two purposes. First, they enable the inductor to filter out unwanted frequencies that can cause interference to the signal. Secondly, they provide a low impedance for certain frequencies, enabling optimal power conversion efficiency.The iron core material prevents the inductor from saturating at high frequencies and helps reduce the overall size of the inductor. This allows for more efficient use of the space in which the inductor is installed and helps to reduce the amount of heat generated.

Conclusion

The 1782R-65H Fixed Inductor is a great choice for high power DC-DC converters, LED lighting, and many other long-range power applications. Its unique construction provides an incredible durability in adverse conditions, while its fixed value makes it ideal for many purposes. Its combination of inductor coil design, iron core material, and two capacitors give it excellent efficiency in power conversion processes, making it perfect for a variety of applications.
